[ADVISORY] Some login IPs to be retired next week
On Monday, 3 August, we’ll be turning off some old IP addresses on our login servers.
These IP addresses have not been in active rotation for over a month, meaning that Residents who use “normal” login procedures won’t notice their loss.
However, we’ve identified a small number of Residents who, at their own initiative or as an attempt to debug various Support requests, have customized their logins with the –LoginURI command line option to point to one of the decommissioned addresses.
It is also possible that some Residents will see their logins failing due to stale DNS caches, either local to their machines or (less likely) maintained by their respective ISPs.
We’ve emailed those Residents who have been employing direct logins.
In the event you find your own login disrupted next Monday, we suggest you first refresh your local DNS cache.
